Answer #1

Drag force= (1/4)(density of air)(Area)(v^2)

D= (1/4)(1.2kg/m^3)(1.4mx1.6m)(15 m/s)^2
D= 151 N

    Consider a Porsche 911 sports car with a mass of 1900 kg. The air drag force at highway speeds can be approximately calculated as: F_drag = 1/2 C p Av^2 where p = 1.2 kg/m^3 is the density of air, A is the front area of the car, C is the drag coefficient and v is the velocity. For the Porsche 911, we can take A - 2.3 m^2 and C = 0.28. What is the power necessary to overcome...

    An object with cross section A is shot horizontally across frictionless ice. Its initial velocity is v0x at t0=0s. Air resistance is not negligible. A 1.8 m wide, 1.5 m high, 1700 kg car with a drag coefficient of 0.35 hits a very slick patch of ice while going 24 m/s . Air resistance is not negligible. If friction is neglected, how long will it take until the car's speed drops to 11 m/s ? To 5.0 m/s ?
